In fact, the working process of the diesel engine with a gasoline engine as a generator set manufacturers, each work cycle has gone through intake, compression, for power, exhaust four stroke. However, since diesel fuel is diesel fuel having a viscosity large generating units than gasoline seller, not readily evaporate, and its auto-ignition temperature but lower than gasoline, and thus the formation of combustible mixture ignition gasoline engine are different. In the intake stroke diesel inhaled pure air. When near the end of the compression stroke, diesel fuel injection pump through the oil pressure up to 10MPa or more, through the injector injected into the cylinder, in a very short period of time is mixed with hot air compressed to form a combustible mixture. Because the diesel engine compression ratio (usually 16-22), so in the end the compression cylinder air pressure up 3.5-4.5MPa generators processors, while the temperature up 750-1000K (and gasoline engine hybrid gas pressure at this point will 0.6-1.2MPa, temperature of 600-700K), much higher than diesel fuel auto-ignition temperature. Diesel generator is a small power plant, means the diesel fuel in the diesel engine prime mover driven generator to power machinery. The entire unit generally consists of diesel engines, generators, control box, fuel tank, starting and controlling the storage battery, protective equipment, emergency cabinet and other components. Diesel generator set in the time of purchase, customers are most concerned about the price of generators, generator sets based on sub-brand there are many, and generator sets different prices are not the same with diesel power, diesel generator manufacturers to introduce you diesel generator prices how to compare. A question, ask the old diesel purchase time, because the use and sale, asking previous repair, replace major components which had to ask what is the problem, in use, in order to understand the old diesel engine has a more comprehensive system. Second, look, look at the signs and the appearance of the old diesel. Which factory to see the production, when the factory from existing how long; look at the appearance of the paint is off, even if the Department of defect, whether the model was eliminated and the like. From signage and appearance to determine the newness of the old diesel engine. Weifang generators _ Weifang Huadong (certified) _ generators provided by the Weifang Huadong Engine Co., Ltd.
